Answer:
(1,1) x=1 y=1
Step-by-step explanation:
-4u=16
U=16÷(-4)
U= -4 To check -4(-4)=16
16=16
I'm not really sure, because 650 marked down by 27% would be 474.5, which is close but not exact.
Hope I helped a little bit, sorry if I'm wrong.
Answer: a one-way ANOVA
Step-by-step explanation:
A One-Way ANOVA Which is also known as the Analysis of Variance is used to compares the means of two or more independent groups in order to determine if there is statistical relationship that is associating both population means are significantly different. A one way Anova test helps determine if the means of two or more groups are different. From the given example the best year to apply would be the one way anova because it would help in determining the difference between the orcs killed by elves, men and hobbits.
I see right away that 3 can be factored out of <span>15xy − 45x − 6y + 18.
The quotient is 5xy - 15x - 2y + 6, so that
</span>15xy − 45x − 6y + 18 = 3(5xy − 15x − 2y + 6) (2 factors)
<span>
or 3 [ 5x(y-1] - 2 [y-3])
